About

Tiehua Chen is a researcher specializing in tele-operated robotic systems, with a primary focus on master-slave bilateral control and force tele-presence. His work addresses critical challenges in remote manipulation, particularly the design of hydraulic servo systems that enable operators to experience force feedback during tele-operation. In his 2007 paper on the "Master-Slave System and Bilateral Servo Control," Chen developed a 2-DOF master manipulator using servo valves and hydraulic servomotors, integrating force information for precise control—a contribution cited 6 times. His companion study on "Force Tele-Presence" further advanced bilateral control strategies, tackling the limitations of symmetric servo valves in direct actuation. Chen also explored the impact of communication time delays in tele-robotics, proposing a virtual reality-based tele-presence system to mitigate this ineluctable issue, as detailed in his 2007 work on VR-enhanced remote operation. With over 18 citations across his key papers, Chen’s research provides foundational insights into force feedback and delay compensation, essential for applications in hazardous environments and remote surgery. His achievements underscore a career dedicated to enhancing human-robot interaction through robust, real-time control systems.
